Let's divide 680521 by 6
The aim is to understand the frequency of 6 in 680521.

Advancing to step 1:
6 divided by 6 is 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 6 away from 6, we end up with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 6

Moving on to step 2:
If we divide 8 by 6, we get 1 and a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtract 6 from 8 to get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 6

Advancing to step 3:
20 divided by 6 is 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 113.0
Deduct 18 from 20 and we're left with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 6

Step 4:
If we divide 25 by 6, we get 4 and a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 1134.0
Subtracting 24 from 25 leaves us with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 6

Let's proceed to step 5:
When dividing 12 by 6, we get 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 11342.0
If we subtract 12 from 12, we get 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 6

On to step 6:
1 divided by 6 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 113420.0
If we take 0 away from 1, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
6 goes into 10 1 times with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 113420.1
Deduct 6 from 10 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
6 can be fit into 40 6 times, resulting in a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 113420.16
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
40 divided by 6 is 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 113420.166
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 113420.166, and the remainder is 0.0004.
